The first part of the exhibition of the Telecommunication Engineering is outlined as the verview of the development of the telegraph technology, from the first practically useable apparatus for the reports transmission Morseoś graving telegeraph /1840/through the invention of the first teleprinter by American Hughes with the printing pressure text to the present teleprinterś technique and telefaxes.

In the Museum exposition attention is focused on the work of the Engineering Faculties of theTechnical Universities in Slovakia. It contains nearly 60 three-dimensional exhibits, including models and mockups, photo documentation of the technical designes and plans of the equipment. The dominant feature of this exposition is a simulated automated workplace with the functional robot APR 20, showing the process of welding. The first display panel in this part or the exposition is dedicated to the memory of the founder of the theory of the steam and gas turbines Prof. Ing. Aurel Stodola /1859-1942/. The photographs on display present the engineering laboratory of the Technical High School in Zürich which Aurel Stodola built up during the nineteen thirties.

In the exposition of the utility and art metal objects the visitor can admire the numerous documents of the rich tradition of the handicraftś skill and the artisticś feel of the craftsmen of the nutal - working handrafts. The collection more than 300 exponats from metal documents the combination of the creative echnical thinking with the style influences and generally valid design. Mining and me allurgy in Slovakia reached in 18th century the top in the world measure. On he introducing of the technical progress the important measure rule had Academy in Banská Štiavnica, that was founded in 1763. Here stinted the experts of the worldś format: Mikuláš Jozef Jacquin, Giovanni Antonio Scopoli, Ignác Anton Born.

The exhibition of the department of the energetistic engines bears the name of Prof. Dr. Ing. Aurel Stodola /1859-1942/ -a world renowned scientist, who became famous in the technical world for his basic theory about the constructing steam and gas turbines. He has been invited from High Technical School in Zürich and from 1892 he has permanent acted as Professor by him founded Faculty the contracting engines, where he became famous in the world as a scientist and high schoolś Professor with his scientific work "Dampf -turbinen und ihre Aussichten als Wärmer-kraftmaschinen"/ steam turbines and their perspectives as thermal engines /, in that he put the basic to the theory that is accepted up to the present days. The collection shows steam engines and steam turbines, water-engines and internal combustion engines.

The collections of the art blacksmithcraft are placed in the entrance part, of the museum. There are exhibited forged objects of applied, decorative and art character. The collection of more than 100 exhibits from the various periods of styles attracts with a combination of the traditional craftsmanship with the creative technical thinking and style influences. The oldest exhibit of the exposition is the gothic iron fitting door called according its place of finding "Leles ’Door". From the period of Renaissance comes the forged door - methalic door characteristic of its renaissance ornament with the original lock. By the bar f rging was applied a rod of iron - it can be seen on the renaissance grave cross with a reliquary.

The exposition of the development of typewriters belongs to one of the most comprehensive collections. It documents the development from the second half of 19th century up to the present times.This collection rightfully deserves attention. With the first attempts to construct the typewriter came investors, who wanted to alleviate the sad destiny of the blind.After the Bratislavian J.W.Kempelen in 1775 there was Frenchman Pingeron in 1780 and Englishman Jenkins in 1784, there was alsothe Italian Pelegrina di Castelnuovo in 1800 and plenty of others.The Father of one of the greatest Slovak scientists from the 19th century Jozef Maximilián Petzval was Ján Fridrich Petzval. He was a talented technician and inventor who constructed and patented a typewriter called the "Polygraph", on the 11th of August 1824 in Levoča.

The historical metallurgy exhibition elucidates the development of metallurgy on a worldwide scale with stress on the rich tradition in Slovakia.The exhibition is installed on the arranged stair and in the rooms on the first floor. There are emphasized the discoveries in metallurgy of iron,non-ferrous metallurgy and forming the metals.In the entry part attracts the visitor the model so-called "Slovak furnace"from 14th century,typical for the Slovak ironś regions. It represents the type of metallurgical shaftś furnace,that with regard to that time level of metallurgical tochnology in Europe was high progresive equipment.

The exposition of Astronomy documents the instrumentation used since the oldest period of time up to the present.The devices such as sundials,astrolabes, armilar spheres triguetrum,celestial globes,atlases,maps,telluromete s,various forms of planetariums,lenticular and mirror telescopes,coronographes up to the devices and instrumentation from the satellites come from the collection funds of Slovak Museum of Technology.More than 100 exhibits are placed in the area of 150 m2.To the preciuos collections belong the collection of the sundials from the 17th -18th centuries,the armilar sphere and the celestial globes from the beginning of the 18th century.
